Overview
The NAD+ Cellular Energy Restoration Protocol targets age-related and stress-induced decline in nicotinamide adenine dinucleotide, a critical cofactor in mitochondrial oxidative phosphorylation, sirtuin activation, and PARP-mediated DNA repair. Clinical use cases include chronic fatigue, post-viral syndromes, neurocognitive decline, metabolic dysfunction, and as an adjunct in substance use disorder (SUD) recovery — particularly opioid, alcohol, and stimulant withdrawal where dopaminergic and mitochondrial restoration appear to attenuate craving intensity and post-acute withdrawal symptoms (PAWS).
Target patients are typically adults over 40 with measurable fatigue, cognitive complaints, or metabolic dysregulation; high-functioning patients pursuing healthspan optimization; or patients in early-to-mid recovery from SUD seeking neurochemical rehabilitation. The stack combines high-dose IV loading (1000 mg) for rapid intracellular repletion with maintenance SC dosing (500 mg) to sustain NAD+/NADH ratios between infusions.
Together, the IV induction and SC maintenance approach mirrors the pharmacokinetic reality that exogenous NAD+ has poor oral bioavailability and a short plasma half-life, requiring either parenteral loading or precursor strategies to meaningfully shift the intracellular pool.
Key Benefits
Restores mitochondrial NAD+/NADH ratio to improve cellular energy, cognition, and metabolic resilience. Adjunct role in substance use disorder recovery for craving reduction and PAWS attenuation.
Mechanism of Action
Direct repletion of intracellular NAD+ drives Complex I-mediated ATP production, SIRT1/SIRT3 deacetylation, PARP1 DNA repair, and CD38-modulated calcium signaling.
Molecular Information
Weight
663.43 g/mol
Type
Dinucleotide cofactor (nicotinamide + adenine, ribose-phosphate linked)
* NAD+ is a small-molecule coenzyme, not a peptide. Poor oral bioavailability necessitates parenteral delivery.

| Consolidation (Weeks 5–8) | 1000 mg + 500 mg | IV every 2 wk + SC 2×/wk | IV + SC |
| Maintenance A (IV-anchored) | 1000 mg + 500 mg | IV monthly + SC weekly | IV + SC |

| SUD adjunct front-load | 1000 mg | Daily × 5–10 days | IV |
Timing · Administer in morning or early afternoon to avoid insomnia. Always co-administer methyl donors (TMG or methylated B-complex) to offset methyl-group depletion. Slow IV rate immediately if patient reports chest pressure, flushing, or cramping.

How to Reconstitute
- 1
Confirm vial label, strength (1000 mg or 500 mg), and expiration date.
- 2
Wipe vial stopper and bacteriostatic water (BAC) vial with separate alcohol swabs.
- 3
For IV: draw NAD+ 1000 mg into 250–500 mL of 0.9% normal saline bag.
- 4
For SC: reconstitute 500 mg vial with 2–3 mL bacteriostatic water; inject diluent slowly down vial wall.
- 5
Gently swirl — do not shake — until fully dissolved. Solution should be clear to pale yellow.
- 6
Inspect for particulate matter or discoloration; discard if present.
- 7
For IV: prime tubing, attach to indwelling IV access, and start at slow rate (e.g., 25 mL/hr) for first 15 minutes.
- 8
Titrate IV rate upward as tolerated; total infusion typically 2–4 hours. Slow immediately if symptoms emerge.
- 9
For SC: draw target dose into insulin syringe; rotate sites between abdomen and thigh.
- 10
Inject SC slowly over 10–20 seconds to reduce stinging; warming the syringe to room temperature improves tolerance.
- 11
Label reconstituted SC vial with date; store refrigerated and use within 30 days.
- 12
Document dose, rate, site, and any adverse reactions in patient record.
Quality Indicators
Clear to pale yellow solution
Properly reconstituted NAD+ should be transparent; deeper yellow or amber indicates oxidation.
Full dissolution within 60 seconds
Powder should dissolve readily with gentle swirling.
Mild stinging on SC injection
Common and transient; mitigated by room-temperature solution and slow injection.
Particulate matter or cloudiness
Discard immediately — may indicate contamination or degradation.
Brown discoloration
Indicates significant oxidation; do not administer.
What to Expect
First infusion often produces transient chest tightness or flushing — slow the drip and these resolve
Most patients report improved energy and mental clarity within 1–4 weeks of loading
Sleep quality often improves; mood stabilization common in SUD recovery context
SC injection sites may show erythema or induration lasting hours — rotate sites
Cognitive metrics (processing speed, working memory) typically improve by week 8
Homocysteine may rise without adequate methyl donor co-supplementation
Non-responders are usually identifiable by week 4–6; escalation rarely changes outcome
Some patients describe improvements in skin quality and hair regrowth at 12 weeks
Inter-individual variability is substantial; track subjective and objective metrics
Late-day dosing can cause insomnia — administer morning or early afternoon
Side Effects & Safety
- IV infusion reactions: chest tightness, flushing, dyspnea, nausea, abdominal cramping (rate-dependent)
- Muscle 'pulling' or tugging sensation during infusion
- SC injection site erythema, induration, transient burning
- Headache, particularly during first 1–2 sessions
- Transient anxiety, irritability, or activation
- Insomnia if dosed late in the day
- Elevated homocysteine if methyl donors inadequate
When to Stop & Call Provider
- Severe or persistent chest pain not relieved by slowing infusion
- Hypomanic or manic symptoms (particularly in bipolar spectrum)
- Signs of hypersensitivity (urticaria, angioedema, bronchospasm)
- New diagnosis of active malignancy
- Pregnancy or planned conception
- Initiation of PARP inhibitor or chemotherapy
